Patented June 18, 1912.

Application filed March 6, 1905. Serial No. 248,555.

To all whom it may concern:

Be it known that we, PETER Marian, a subject of the King of Prussia, and resident of N ordstrasse 27, Cologne-Xippes, Germany,.and KARL Nunsn, a subject of the King of Prussia, and resident of Les'singstrasse 22, Altona-on-the-Elbe, Germany, have invented certain new and useful Improvements in Type-Writing Machines; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of. reference marked thereon, which form a part of this specification.

-The subject of our invention is a typewriting machine which presents the here inafter described differences and advantages as compared with the machines heretofore known.

In the accompanying drawings;-Figure 1 shows the machine in longitudinal section, and Fig. 2 in plan; Fig. 3 shows in plan the device for setting the type-carrier. Fig. 4 is an underside view of the machine. Fig. '5 shows a type-carrier in plan, drawn full size, While-.Fig. 6 is a vertical section. Fig. 7 shows the carriage-feed-mechanism in elevation, and Fig. 8 in plan. Fig. 9 is a front elevation showing the device for feeding the carriage backward, while Fig. 10 shows the said device in side elevation.

The key-levers 2, which are capable of turning about a common axis 1, are arranged in a known manner in two groups, of which those on the left-hand cause the type-carrier to turn to the left, and those on the right-hand cause it to turn to the right (Fig. 4). This rotation is produced v by means of the. two bell-crank-levers 4,

which are pivoted at 5 arms beneath the key-levers bear a cross-bar 6. In this cross-bar 6 are arranged adjustable screw-pins 7 the ends of which take the pressure of the key-levers 2 and transwit it to the bell-crank lever 4. Exact regulation of the throw of the cross-bars and therefore also of the angle of oscillation of the segment can be obtained for each key-lever 2 by turning these screws to the rigi'ztor to the left-hand. The upwardly-extending arms of the bell-crank levers each engage in a slot 9 in the arms 11 mounted and of which the on the hollow shaft 10 (Figs. the keys are struck, produce rotation of the shaft 10 in one or the other direction. In the position of rest of the two levers l. the fingers 12 of the arm 11 lie on the ends of the levers l, so that the hollow shaft 10 hearing the typecarrier is locked in the mid position. 011 the other hand. the bent finger 13 of one arm 11 locks Lhe corresponding lever l and with it the corresponding group of key-levers, if the other arm 11 has been turned by the correspond 2, and; as

mg lever f. The position of rest of the two arms is defined by stops ll.

' The hollow shaft 10, which is capable of turning about the vertical spindle 15, carries with it in its rotation the segmental type-carrier by means of an eccentric pin 16, which is secured thereto and bears a fork shaped piece 16 (Figs. l, 5, 6.) The typecarrier consists of three segmental frames 60, which are rotatably mounted on the upper end of the shaft 15. The several types 61 are arranged at equal distances aparton the periphery of the segmentpieces in such a manner that, when the typehannner is thrown forward, only the type brought in position for the time being is caused to print. Each type 61 is acted upon by a spring 62 and is guided in the walls of the segment-pieces in such a'manner that turning or twisting of the'types is impossible. This is effected by making the front part of the rod or shaft bearing the type of rectangular form, while the rear part of the said rod or-shaft is made round and is guided in a correspondingly-shaped guide in the rear wall of the segment-piece. As the type is thrown forward, the spring 62 arranged between the inner edge of the outer wall of the segment piece and the round part of the shaft or rod bearing the type, is compressed, so that it can return the type to its initial positlon after the blow has been struck.

The hollow shaft 10 is provided at lts lower end with an arm 17, the forked end of which extends to the locking pins 18 (Figs. 1, 2 and These pins are arranged 1n the arc of a circle, and guided 1n holes in the arc-shaped frame 19, and extend .through the base-plate 20 to arms 21 extending from the key-levers 2, which arms hold the pins, when in the position of rest, at such a he ght that the ends of the arm 17 can go freely rately into the printing position. The lockingpins 18 either rest, by reason of their weight, on the arms 21, or their lower ends are caused by small spiral springs 23 (Fig. 1) to follow with certainty the downwardf motion of the arms 21.

The arrangement of the locking pins 18 above the base-plate 20 insures their being easily accessible and permits the shaft for turning the segmentparts to be made hollow so that the spindle 20 15 can be moved vertically in order-to adjust the height of the segment-pieces. For this purpose, the spindle 15 is securely guided at the bottom in the base-plate 20 and at the top in av cross-piece 24 connected 25 to the base-plate 20.

The adjustment of the height of the typesegments is efiected in the following manner: The typ e carrier-shaft 15, which is prevented from turn ng, 1S connected at its lower end to two levers 71 (Figs. 1 and 1) arranged beneath the base-plate 20, which levers are secured at their other ends'to the ends of two hollow shafts 72 turned toward the center line of the machine, which hollow shafts are rotatably'arranged. on a shaft 73 mounted on the frame. The other ends of the hollow shafts are each connected to a key-lever 74-, which levers move in guides 7 5 arranged on the underside of the base-plate 20. One of the two key-levers 74 effects the lifting of the type-carriershaft 15' in such a manner that the middle segment-piece is brought into the printing position, while the other key-lever Tet lifts 5 the shaft 15 to such a height that the lower segment piece is brought, into the printing "position. In order to be able to regulate the travel of the two key-levers 74 and thereby to effect the correct adjustment of the two lower segment-pieces into the printing position, set-screws 76 are arranged at the lower ends of the guides 75, so that the vorresponding key-lever can only be depressed until it strikes against the correaasponding set-screw 76. For returning the ype-carrier-shaft- 15 to its position of rest, the spiral spring 84 acts on 1ts lower end.

the printing position is carried along by the rotation of the hollow shaft 10 during the depression of a key by the aid of the forked Q5 part. 16 and the type corresponding to the key is brought into the printing position. By dividing the type-carrier into three, it

is possible that in all cases only that seg- 4 ment-piece shall be turned which is opposite to the limbs of the part 16. In order to prevent the other parts from being carried along therewith, they are locked by a pin 85 fastened to the crossbar-24, which has a recess 86-at the height of the forked part- 16 (Figs. 1 and 6) so that only the segment-piece at the same height can be turned.

In order to enable each of the two lower segment-pieces G0 to be held in the printing position for a longer time, withoutitbeing necessary to keep one of the" two keylevers 74 continuously depressed, a locking device is provided for each of the two keylevers. This locking device consists of a locking pin 78 (Fig. 1) which is movable in a guide 771nounted on the base-plate 20 and which is adapted to engage in a recess 79 in the lever 71. The pin is acted upon by a spring 80, which tends to depress it, and bears at its upper end a head 81, which has a small pin 82 on its lower edge. This pin normally lies against the upper surface of. the guide 77 and therefore holds the locking pin 78 out of engagement. with the recess 79, which however during rotation of the head 81 can snap into ahole 83 in the guide 77 by the action of the spring 80, so that the l'ockingpin 78 can engage with the pin recess 79 of the lever 71 and thus hold the I key-lever 741 in its depressed position In order to feed the carriage, two transverse levers 14:, 15 are arran ed close beneath the key-levers 2 (Fig. 4% and extend over the whole width of the two groups of keys. The front lever 44: is moved by the left-hand group of key-levers andis capable of turning about its right ha nd terminal point at 17. The rear lever 45 is moved by the right-hand group of key-levers and is capable of turning about the left-hand terminal point at 16, The levers 44, held up by springs 49 and are provided at their free ends. with slots whereby they are guided on the pins of the standards- 4 and 4:7. The two transverse levers 1 1, 45 thus move in opposite directions during the manipulation of the rey-levers, and act on a 45 are v shortlever 2 which is likewise capable of turning a 1 out the axis 1. This lever 12 abuts against a stop '13 and engages with the under-side's of the levers 1 1, so by means of an arm 12 (Figs. 1 and'et,

The lever 12 is connected by means of a rod 11 with the lever 32, which is pivoted at 31 and bears a locking pawl 30 for engaging with the teeth of the ratchet wheel 39 (Fig.

of the draws the locking pin not take place until the type-carrier has been set by the corresponding key. The turning of the lever 32 with the locking pawl thus has for its result that the locking pawl acts on the lever'34c (which is capable of turning about the axis 33) in the opposite direction to that. in which the said lever is moved by its controlling spring 35, whereby the locking lever 37 (which is capable of turning which engages with a slot in the locking pin '26 for locking the segment-pieces 60 in the printing position) is released by lever 34. By under the action of the spring 28, can rise and effect the locking of the type-carrier by entering a hole, Corresponding to the type selected, in the arc shaped piece 29 secured to the hollow shaft 10. If now, on releasing the key-lever, the ratchet-wheel 39 is released by the locking pa'wl 30, so that itcan turn through one tooth or step and effect the feed of the carriage, the tooth of the wheel 39 lying within reach of the lever 3? acts on the lever 37, so that the latter 26 down again and is finally held in its position again by the pin 38 of the lever Since both levers 44, 45 are provided with adjusting screws 48, the action of all the key-levers can be regulated so that the locking thereof only takes place after the type-carrier has been set. The driving of the hammer 51 (Fig. 1) whichv produces the blow struck by the type. is effected from the carriage-feed mechanism by means which do not form part of the present invention.

I11 order to render it possible to write on one and the same machine with two or more different sizes of space between the characters. it is necessary to provide both the racks of the carriage, and also the corresponding wheels of the carriage-feed-mechanism, with teeth of two or more different pitches. According to which size of space between characters is desired, one of the toothed wheels mounted on the sleeve of the driving shaft is coupled to the said sleeve whereby a longer or shorter distance of feed of the carriage is obtained. The coupling of the toothed wheels mounted on the sleeve is effected by the movement of a feat-her 52 (Fig. 8) which can be moved in a longitudinal groove in the sleeve by means of the screw nut- 53, so that the front end 52 of the feather couples either one or other of the two toothed wheels 50, with the sleeve. The two latter wheels have teeth of difierent pitch, so that, each time a key is struck, the carriage is fed through a different distance, accordingly as one or other wheel is coupled to the sleeve.

In order to obtain a rapid and certain setting of the carriage or slide to any desired point in the rearward direction, the

about the axis 36 and the pin 38. this means, the pin 26,

arrangement hereinafter described is employed: This arrangement consists of a feed-lever Ill (Figs. 9 and 10) which is pivoted at 115 and is provided at one end with a feed-pawl 116 which en ages with the teeth of one of the carriageeed-wheels 50, 50. At the other end, the lever is connected to the key-lever 118, which is pivoted at 119 to the base-plate 20. A standard-l20, which at the same time forms a guide for the lever 114. contains a spring 121 which always tends to hold the feed-pawl out of engagement with the feed-wheel 50 or 50.

By depressing the key-lever 118, the pawl comes into engagement with the feed-wheel and effects the backwardmovement of the carriage. By means of an elongated aperture or slot 122 formed in the key-lever 118, the throw of the key-lever, and thus also the distance through which the carriage is fed backward, is limited. According to the size of the said slot, the carriage can be noved back through-a distance correspondling to the width of, for example, one, two, or more types.
